The first mentions of the numerals from 1 to 9 in the West are found in the Codex Vigilanus of 976, an illuminated collection of various historical documents covering a period from antiquity to the 10th century in Hispania. The first Arabic numerals in the West appeared in the Codex Albeldensis in Spain.
Ī popular myth claims that the symbols were designed to indicate their numeric value through the number of angles they contained, but no evidence exists of this, and the myth is difficult to reconcile with any digits past 4. Al-Uqlidisi later invented a system of calculations with ink and paper "without board and erasing" ( bi-ghayr takht wa-lā maḥw bal bi-dawāt wa-qirṭās). The numerals themselves were referred to in the west as ashkāl al‐ghubār ("dust figures") or qalam al-ghubår ("dust letters"). The use of the dust board appears to have introduced a divergence in terminology as well: whereas the Hindu reckoning was called ḥisāb al-hindī in the east, it was called ḥisāb al-ghubār in the west (literally, "calculation with dust"). Ĭalculations were originally performed using a dust board ( takht, Latin: tabula), which involved writing symbols with a stylus and erasing them. Some amount of consistency in the Western Arabic numeral forms endured from the 10th century, found in a Latin manuscript of Isidore of Seville's Etymologiae from 976 and the Gerbertian abacus, into the 12th and 13th centuries, in early manuscripts of translations from the city of Toledo. The Western Arabic numerals came to be used in the Maghreb and Al-Andalus from the 10th century onward. They show three forms of the numeral "2" and two forms of the numeral "3", and these variations indicate the divergence between what later became known as the Eastern Arabic numerals and the Western Arabic numerals.
The oldest specimens of the written numerals available are from Egypt and date to 873–874 CE. In the eastern part of Arabic Peninsula, Arabs were using the Eastern Arabic numerals or "Mashriki" numerals: ٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩ Īl-Nasawi wrote in the early 11th century that mathematicians had not agreed on the form of the numerals, but most of them had agreed to train themselves with the forms now known as Eastern Arabic numerals. The reason the digits are more commonly known as "Arabic numerals" in Europe and the Americas is that they were introduced to Europe in the 10th century by Arabic speakers of Spain and North Africa, who were then using the digits from Libya to Morocco. The numerals have found worldwide use significantly beyond the contemporary spread of the Latin alphabet, and have become commonly used in the writing systems in where other numeral systems existed previously, such as Chinese and Japanese numerals.Įvolution of Indian numerals into Arabic numerals and their adoption in Europe European trade, books, and colonialism helped popularize the adoption of Arabic numerals around the world. It was in the Algerian city of Béjaïa that the Italian scholar Fibonacci first encountered the numerals his work was crucial in making them known throughout Europe. The term numbers or numerals or digits often implies only these symbols, however this can only be inferred from context. The Oxford English Dictionary differentiates them with the fully capitalized Arabic Numerals to refer to the Eastern digits. They are also called Western Arabic numerals, Ghubār numerals, Hindu-Arabic numerals, Western digits, Latin digits, or European digits. The term often implies a decimal number, in particular when contrasted with Roman numerals.

They are also used for writing numbers in other systems such as octal, and for writing identifiers such as computer symbols, trademarks, or license plates. They are the most commonly used symbols to write decimal numbers. Arabic numerals are the ten numerical digits: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
